My second year timetable (second term) had a few anomalies. Like classes that didnt exist, lectures that turned out to be in land management instead of psychology, god knows what else.
Of course I went and organised all my practical classes first day back and the rescheduled lectures turned out to overlap them. And then it turned out impossible to reschedule the practicals. That was a year of hell, and a contributing factor to why I failed second year.
That and not working
The moral - dont trust lecturers, secretaries or computers. And get a map, no university is complete without the Building That Cannot Be Navigated.
